Hi Milehigh,

I have done some calculations, based on coil data from the Nichelson paper I referred to above.

Given: air core coil OD=4"   and number of turns=43

I looked for the possible wire diameter the coils were wound because I disagreed with the impedance divider network you supposed whereby the coil is one element and a one Ohm resistor is the other element in the divider network (see my EDIT comment below).

So I found from the calculations that the length of the wire (any coil was wound from) was 13.72 meter. Then I looked up wire gauge tabelle with electrical resistance values and figured that Nichelson must have used OD=0.56mm (copper) wire, the nearest awg is #23 (0.57mm).

The reason I disagree with your voltage divider idea (see EDIT)  is that while it is true Nichelson et al used 1 Ohm in the denominator of the "voltage gain" formula but now it is clear (for me) that the 1 Ohm came from the coil DC resistance.  Further, if you have a look at Figure 1 in the above paper, the network analyzer (generator and receiver) ports were directly "bridged" with any one coil during the measurements, there was no 1 Ohm resistor used (see EDIT).  I looked up a manual for the HP3577B and its generator output impedance is 50 Ohm, its receiver input impedance can be chosen to be either 50 Ohm or 1 MOhm with 30pF parallel capacitance. (It is very reasonable to assume that they used the 50 Ohm input for the receiver side too.)

Now there is one more thing: have you noticed since then that the formula they used for calculating the voltage gain is nothing else but the Q of a coil i.e. X_L/R  (inductive reactance divided by the wire resistance)?  You mentioned that the calculated voltage gain was the reactive impedance for each coil.

I think my above calculations and deductions are correct (if you notice any issue, or disagree,  please comment).

Gyula

EDIT  Where I inserted the  EDIT above, I somehow avoided to consider that you eventually stated: "Of course there is no one-ohm resistor anywhere to be found and no impedance divider network."   Sorry for this.  All the other things I wrote I consider still valid.

  I can understand how by use of resonance we can store energy.  Not unlike a battery or a catapault of a flywheel-etc.  The part I don't get about Tesla and his magnifying transmitter is his claim that the natural medium offered no resistance to really high potentials at high frequency.   What he may have been doing is creating plasma emanating out from his terminal in the air.   This would greatly increase the mass in play.  The plasma would electrically extend the terminal.   I don't see him creating a plasma construct from radiator to receiver without encountering huge amounts of difficulty.  But he could make one big ass sky conductor.  By excluding any sharp edges or defects his sky terminal would not create the lightning bolts he is famous for.  In fact the guys who have those sharp little pipes hanging out of a Tesla transformer are using Tesla's safety circuit.  I have created a weird plasma thing before.  It isn't bright white crackling zig zag lightning looking stuff.  It is  more like a flame.  I used an iron coil (by chance) mid-tapped with the anode of an old tv set attached to the middle.  It created ion wind at least a foot away.  The flames were coming out of both ends of the iron wire and bowing towards each other along a smooth circumference.  I imagine if I put information riding the hv flyback somehow the flames would have danced.  I gotta repeat this experiment again.  I've had this old microwave oven sitting around just too busy to get past the one way screws built for guys like me.  If tesla did make a huge antennae made out of plasma instead of conventional metals,  any wave activity in the plasma would act just like wave activity in an antennae mast.  I haven't seen any broadcast antennae's 2 or 3 miles high with a 20 mile radius at the top.  I really don't know what the fuck he was up to in NJ but I believe a metal object like an airplane flying over that tower would have let go a couple of electrons and look like a ship lit up with St. Elmo's fire right before the crackler blows the mast to shit.

I don't think he said that, do you have a reference "in context" for that claim ?

Tesla had two separate and distinct uses for the Magnifying transmitter, one was the transmission of signals which could be done at a higher frequency because of the need for less power and the other was the transmission of power which needed to be done at lower frequencies to avoid losses. Tesla often spoke of the losses.

A quote from Tesla "in context" showing the claim or it didn't happen. I think I know the text you refer to but I think it is most likely misunderstood, and to reply to a claim it needs to be considered in the context it was made.

discussing hearsay is pointless and causes more problems than it solves, IF you wish to discuss a claim made by Tesla or anyone else for that matter you should provide a quote "in context" containing the claim and a reference for where it was taken from. Otherwise it can't be verified as an actual claim made.

Cheers

@farmhand your right.   It may not have been in reference to his wireless transmission of power.  I took the liberty of assumption that he was rendering the natural medium conductive in the magnifying transmitter.  If you look at the progression of patents filed on transmission of energy without wires he first has a wire strung between transmitter and receivers.  Then the wire disappears. My best guess is that he had the high voltage minute duty cycle energy input to simulate the electric field flux changes of an ultraviolet wave.  This would ionize the air molecules rendering it into a plasma.  Then the low frequency information caused plasma wave activity.   No idea as to what plasma with low frequency wave patterns does as far as radiation of energy but it would be interesting to find out.

cheers

    I believe the information below may explain what Tesla was up to with the magnifying transmitter.  If we add the Earth into the transmission line standing waves would begin to develop in the Earth and extensions of the Earth like his receivers.  The voltage between nodes and antinodes developed within the reciever could be used to charge local capacitors.  Or the magnetic field changes associated with the currents inside the transmission line could drive various transformer secondaries.  This would effectively insert a dummy load to the transmission line superimposed oscillations.  This would allow more waves to leave the transmission line than are reflected.  Power then flows from scource to load.  http://www.allaboutcircuits.com/vol_2/chpt_14/6.html
